All three incidents are believed to be part of a bloody gang conflict that has wracked north Minneapolis for months.

The most recent attack — thought to be tied to the fatal shooting of 23-year-old Anthony Stubbs in the early morning hours of Friday — occurred about 2:34 p.m. when rival gang members exchanged fire in the middle of the 4300 block of N. Humboldt Avenue, police said. No one was injured in that shooting, but several homes were struck by gunshots, Fourth Precinct inspector Mike Kjos said Wednesday.

He said that detectives have issued a probable cause pickup for a suspect, whom they believe may information about Stubbs' death.

The incident was preceded by another shooting on the same block, at about 10:38 p.m. Saturday, which police said they believe was also connected.

No one was injured in that incident either, but the shootings prompted city and police officials to hold a hastily-organized community meeting on Wednesday night at the Webber Community Center.

Kjos sought to reassure skittish residents at the meeting by saying that the department had authorized overtime pay for officers to spend more time in the area to help stave off further violence.

He said that residents can actively oppose crime by organizing block clubs and calling 911 when they witness suspicious activity. But several residents complained that even when they called police, officers were often slow to show up.

Others described fearing for their lives when gunfire broke out on an otherwise quiet Sunday afternoon.

Kjos said the violence likely stemmed from a raging gang war in north Minneapolis, in which “splinter groups” have aligned themselves to form two larger factions, the High End and Low End, their territory roughly divided by West Broadway Avenue.

"Gun violence between various street gangs in North Minneapolis has increased tremendously, this is mainly due to YouTube rap videos disrespecting the opposite gangs dead gang members or disrespecting high ranking members of the rival gang,” police wrote in recent court filings.

Minutes after the homicide on Friday, police arrested three men in a car that was seen fleeing the scene, one of whom was later released, "pending further investigation," police said. Police also said a gun was recovered from the car.

A department spokeswoman said last week the other two suspects — a St. Paul man, 23, and a Brooklyn Park man, 25 — were booked into Hennepin County Jail for violating probation for previous offenses. One of the men is a member of the Low End-affiliated street crew called the Black T Gang, or BTG, court records show.

Though police said the investigation is gaining momentum, no one has been charged so far in any of the shootings.

Hennepin County Attorney Mike Freeman said one of his biggest regrets as the county’s top prosecutor was using grand juries to investigate the shootings of civilians by police, admitting that the process lacked transparency.

Freeman’s comments came during an often raucous public forum on police-community relations Saturday evening that brought together residents and law enforcement officials for what organizers envisioned as a constructive dialogue between both sides. But the event ended abruptly about an hour after it began, when a Q&A session devolved into a shouting match.

“I made a mistake in the first 17 years of being a county attorney by using a grand jury” to investigate cop-involved shootings, Freeman said in response to an audience question about whether he has any regrets.

The session also was marked by a series of outbursts from the audience, including Clark's father, James Clark, who at one point shouted: "We're tired of having a bunch of lies and that's all we're hearing."

Minneapolis Deputy Police Chief Medaria Arradondo, police union President Lt. Bob Kroll, Hennepin County sheriff’s deputy Kellace McDaniel and Kevin Lindsey, commissioner of the Minnesota Department of Human Rights, also took part in the panel discussion, at Wayman African Methodist Episcopal Church on the city’s North Side.

Freeman denied that he had mishandled the case of Jamar Clark, who was killed during a confrontation with two Minneapolis cops outside a North Side apartment building last fall.

The two officers, Mark Ringgenberg and Dustin Schwarze, were later cleared of any wrongdoing in separate state, federal internal investigations and are back on duty.

Freeman, who was repeatedly interrupted as he spoke, said Saturday that he felt “terrible” about Clark’s death — which set off weeks of furious protests and fueled a fierce national debate about police treatment of blacks — but defended his decision not to charge the officers.

Clark’s family members have said they plan to file a wrongful-death lawsuit against the city, contending that Clark’s shooting could have been averted.

Arradondo, a lifelong North Sider, said that the department has sought to come to grips with law enforcement’s troubled history of abuses against minorities, citing the example of a police chief who refused to intervene when a white mob lynched three black men outside a Duluth police station in 1920, famously saying: “I do not want to see the blood of one white person spilled for six blacks.”

"We have to respect that this badge has not always been representative of" justice for people of color," Arradondo told the audience.

Organizers said they hoped the meeting would help repair relationships between police and the community, particularly the ethnically diverse neighborhoods of north Minneapolis.

But the event, which was scheduled to run until 6:15 p.m., ended about an hour early, as the crowd grew increasingly agitated and accused the panelists of dodging tough questions.
